# Orbit Capable SpaceX Starship May be About 3 Months Away

Elon Musk believes the second test tank could perform significantly better if pressurized with a cryogenic liquid. The steel will cryogenic harden when exposed to extremely cold temperatures which will make it stronger.

Starship 9 meter test tank made 7.5 bar at room temp. It had a small leak at a weld doubler. It will be repaired and retested at cryogenic temperatures.

SpaceX’s second Starship test tank has 125% safety margin.

Elon says SpaceX can immediately start building the first Starship for spaceflight.

1. I think Update was asking whether these are absolute or gauge values. Though throwing psi into the question is confusing.

That is, whether the 6.0 bar is 1.0 of normal atmospheric pressure, plus 5.0 bar of overpressure. Or if it’s just 6.0 bar of overpressure.

If 8.4 is 1.4 times 6, then they are using the full value of 6, not just the (6-1) which is what you would be multiplying by if it was absolute values.

So I think that, if the math is as given, that they are using gauge pressure, not absolute.
